摘要
本文基于平准化度电成本(LCOE),对比分析抽水蓄能与电化学储能在每日一充一放、两充两放及考虑/不考虑充电成本场景下的经济性。结果表明:(1)在调用次数相当时,抽水蓄能经济性显著优于电化学储能;(2)随着电化学储能初始投资降低、循环次数增加以及抽水蓄能电站初始投资增加,两者经济性差距逐步缩小。
This study conducts a comparative economic analysis of pumped hydro storage(PHS)and electrochemical energy storage(EES)under different operational scenarios,including one-daily-cycle,twodaily-cycle,and scenarios with/without charging costs,using the Levelized Cost of Energy(LCOE)as the evaluation metric.The results reveal:(1)Under equivalent cycling frequencies,PHS demonstrates significantly superior economic performance compared to EES;(2)The economic gap between the two technologies gradually narrows as EES initial investment decreases,cycle life improves,and PHS construction costs rise.
